1. Clouds Types and Weather

2. Cloud Formation Formed when air is cooled and condensation occurs

3. Cloud Types

4. Cumulus (heap) Description – Puffy, piled up Altitude – Low or middle Weather Predicted – Nice, sunny weather

6. Stratus (layered) Description – Light gray, covers sky, puffy, layered Altitude – Low Weather Predicted – Hazy and sometimes drizzly

8. Nimbostratus (rain, layered) Description – Flattened with layers, very dark gray, covers sky Altitude – Low Weather Predicted – Long, hard rains

10. Altocumulus (high, heap) Description – Layers of cotton balls, puffy Altitude – Middle to high Weather Predicted – May bring rain or snow – On a warm day, thunderstorms later

12. Cirrus (curl) Description – Wispy, curly, thin Altitude – High Weather Predicted – Nice at first, signal a change in the weather

14. Cirrocumulus (thin, heap) Description – Small layered puffs, fish scales Altitude – High Weather Predicted – Usually seen during winter – Fair but cold weather

16. Cumulonimbus (heap, rain) Description – Anvil shaped, thunderhead Altitude – Low to high Weather Predicted – Thunderstorms and severe weather, sometimes tornadoes

33. Sequencing – Put in order Water vapor condenses on smoke, dust, salt, and other small particles suspended in the air The relative humidity of the air increases Warm air rises and cools Air eventually becomes saturated Millions of tiny drops of liquid water collect to form a cloud
